Easy raid provides words for a supposer (1,4,3)
I believe the answer is:
i dare say
'words for a supposer' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'easy raid provides' is the wordplay.
'provides' indicates anagramming the letters.
'easy'+'raid'='easyraid'
'easyraid' anagrammed gives 'I DARE SAY'.
Can you help me to learn more?
(Other definitions for i dare say that I've seen before include "It wouldn't surprise me" , "Probably" , "It's possible" , "one might suppose" , "Maybe" .)
